We have received a lot of questions from our TAP customers and beta users regarding how and where to configure certificates for encryption and signing of AS/2 messages and MDNs in BizTalk Server 2006 R2. To that end, our resident expert Yury Bogucharov posted some help on the MSDN forum (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1633486&SiteID=1) for R2 EDI. I thought that it would also make a good blog post so I reformatted Yury's message into table format and am posting it here for the benefit of all. Thanks Yury!
